1. Lol the Cloud isn't going anywhere. This is the future of computing, and as the form changes, mutates, evolves, the best positioned companies such as Amazon and Microsoft will have the advantage in being able to lead that transformation.
2. AI is definitely not a toy. I am an AI practitioner, meaning that I tend to recognise the applications of AI whenever I see them, and I can confidently tell you that it's already everywhere. AI is becoming mainstream, and to call it a toy does not pay you any compliments. Your not seeing sentient assistants or robots everywhere doesn't mean AI is a toy. The applications of AI in search, computer vision, robotics, medicine, among other fields are well and alive today, making a big impact on the world. Perhaps you should look a little well at the field before calling AI a "toy"
3. Microsoft is not dead. As I type this, it is the third most valuable publicly traded company in the world, so it's disingenious to insinuate that Microsoft needs reviving. The foldable device is intended to launch a new device category, just as the surface devices did, not to single-handedly propel Microsoft to world domination.
4. Lol. The Microsoft that Satya took over was one with a toxic culture, which stifled innovation and was haemorraging talent, which is why the Ballmer years were so bad. Terry Myerson was never particularly beloved at Microsoft, and barely had many successes, being a vestige of the old Microsoft, the toxic Microsoft. I've noticed that some people are reading some babble from some guy who works at Google (as if he'd say good things about Microsoft's future), and believing that "Windows is dead". Windows is not dead, but is rather evolving. The rollout of Windows Core OS and compatibility with the ARM architecture is part of the evolution of Windows, which is a long process, not something that occurs at the snap of a finger.
Satya Nadella has a vision for Microsoft, which has been rolled out over the course of the past few years. This reorganization is to position Microsoft for the future, hence the consolidation into the new Experiences and Devices group. Windows is evolving into an experience, one that spans multiple devices across multiple form factors. That is not death, but the natural evolution of Windows, and Terry Myerson's departure is just a part of that (and I can say that Microsoft employees are not sad to see him go).
I get that the Windows Phone debacle broke a lot of trust in Microsoft, but it shouldn't warrant the parroting of ridiculous, unfounded narratives. Call me a ******, but Satya Nadella is one of the best things to happen to Microsoft this decade, and the future is definitely bright, whether you see it or not. Nadella's vision is coming to life, and it's promising for Microsoft.
